Re: Cal 31 Propeller Question
Thanks everyone for the responses. I did a new bottom job just before making the trip...its clean. Don't have a tachometer, but throttle was pushed to the stops and no black smoke. I am going back down to Carrabelle, FL (I live in Tennessee) next week and will measure the prop while there. Will be able to report that in a week or so.
Any idea what size props are being used on a Universal 5416 with a 31 foot boat? The Cal is not very heavy (9360 lbs). However, I estimate the loaded weight was around 11,000 lbs.
Looks like i can buy a used prop at Minney's in California and have employed several online prop sizing calculators to narrow down the selection. If they will take returns, I might buy several sizes and compare performance. Have asked for one of those optical tachometers for my birthday to better understand what is happening, per Overboard's input.
